They are the most comfortable sheets this is why I purchased a 2nd set. I ordered a king size set which run small; the fitted sheet sides are to narrow and do not cover the mattress and do not tuck underneath which leads to the corners coming off the mattress while sleeping. Also the flat sheet is to small as well and does not tuck under the foot of the bed, and to short to fold over at the head area. According to the dimensions listed on the website it should fit properly.
